MINIATURE 3049E SERIES IEPE ACCELEROMETERS

NOTE: IEPE is an acronym for Integrated Electronics Piezoelectric types of low impedance voltage mode sensors

with built-in amplifiers operating from constant current sources over two wires. IEPE instruments are compatible

with most other manufacturers' comparable systems.

OPERATING GUIDE

10 mV/g AND 100 mV/g

HERMETICALLY SEALED AND CASE ISOLATED

NOTE:

Series 3049E Series features hermetically sealed construction

and electrically isolated case for "off-ground" performance.

Hermeticity is obtained by all-welded construction and glass-to-

metal sealed connector. Case material is titanium. Signal

ground return is electrically isolated from the mounting surface.

This guide contains:

1) Operating Instructions, Series 3049E Series.

2) Outline/installation drawing, Series 3049E Series

3) Specifications, Series 3049E Series

4) Paper, "Low Impedance Voltage Mode (LIVM) Theory and

Operation"
